On the base steel sheet
1. Hot dip zinc coating, hot-dip aluminum coating, Phosphate conversion method has been adopted so that a top coat can be strongly adhered to it.

2. Epoxy primer coating to which anti-corrosion materials are added.

3. Acrylic seal coating to which anti-corrosion materials are added. As there are three protective films additionally, it has much more excellent adhesion power.  

4. 100% acrylic resin opaque base coating.

5. It color lasts for a long time as it is completely covered with carefully-selected crushed volcanic rock.

6. As it is coated with 100% transparent acrylic resin one mere time and it contains fungicides, it can restrain the growth and development of moss or fungi.

Beneath the base steel sheet
7. Hot dip aluminum coating like the Item No. 1 of “On the base steel sheet”
8. Epoxy coating like the Item No. 2 of “On the base steel sheet”
9. The functions of waterproofing and anti-corrosion have been greatly improved thanks to the polyester backing. (The best waterproofing layer formation with 9 protective layers)




Galvalume
Galvanized steel is steel that has gone through a chemical process to keep it from corroding. its mixture of aluminum(55%), zinc(43.4%) and silicon(1.6%). The steel gets coated in layers of zinc oxide because this protective metal does not get rusty as easily. The coating also gives the steel a more durable. For countless construction materials or industrial applications, galvanized steel is an essential fabrication component.
